“…With the evolution, the Unicode was proposed in 1991 [30]. There have been many kinds of TABLE II COMPARISON BETWEEN THE PRSPC-TDC AND THE CONVENTIONAL TDC APPROACH encoding algorithms available for the high-speed communication dc balance, which are 4b/5b, 8b/6t, 8b/10b, and so on [31], [32]. Compared with the conventional communication encoder algorithm, such as the famous 8b/10b or 64b/66b encoding algorithm, the comb-wave modulation algorithm is a more facile approach.…”

Abstract-Pseudorandom single photon counting is a novel time-resolved optical measurement method, which is advantageous over convention techniques in terms of data-acquisition speed and system cost. As a critical component of the pseudorandom single photon counter, the photon arriving time digitizer should be storage efficient for a high photon counting rate, while maintaining good time accuracy. We report an ultra storage-efficient time digitizer for a pseudorandom single photon counter in this paper, which is based on the asynchronous serial communication and can store the arriving time of every photon in 1-b memory space. In addition, a novel comb-wave modulator is proposed to achieve the dc balance required for asynchronous serial communication. Our prototype implemented on field-programmable gate arrays provides a time resolution of 400 ps. It can register up to 4.2-Giga photon arriving time tags with 1024 32-b memory space.Index Terms-Asynchronous serial communication, single photon counter, time digitizer.

Activation Process of ONU in EPON/GPON/XG-PON/NG-PON2 Networks

et al. 2018

This article presents a numerical implementation of the activation process for gigabit and 10 gigabit next generation and Ethernet passive optical networks. The specifications are completely different because GPON, XG-PON and NG-PON2 were developed by the International Telecommunication Union, whereas Ethernet PON was developed by the Institute of Electrical and Electronics Engineers. The speed of an activation process is the most important in a blackout scenario because end optical units have a timer after expiration transmission parameters are discarded. Proper implementation of an activation process is crucial for eliminating inadvisable delay. An OLT chassis is dedicated to several GPON (or other standard) cards. Each card has up to eight or 16 GPON ports. Furthermore, one GPON port can operate with up to 64/128 ONUs. Our results indicate a shorter duration activation process (due to a shorter frame duration) in Ethernet-based PON, but the maximum split ratio is only 1:32 instead of up to 1:64/128 for gigabit PON and newer standards. An optimization improves the reduction time for the GPON activation process with current PLOAM messages and with no changes in the transmission convergence layer. We reduced the activation time from 215 ms to 145 ms for 64 ONUs.
